JOURNAL OF ETHNOPHARMACOLOGY 2024; 327:118048. [PMID: 38484955 DOI: 10.1016/j.jep.2024.118048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Revised: 03/07/2024] [Accepted: 03/11/2024] [Indexed: 03/20/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Sleep problems, according to Traditional Chinese medicine (TCM) philosophy, are attributed to the imbalance between yin and yang. Zhumian Granules, also known as Sleep-aid Granules or ZG, are a traditional Chinese herbal remedy specifically designed to alleviate insomnia. This formula consists of many components, including Wu Wei Zi (Schisandrae Chinensis Fructus), Suan Zao Ren (Ziziphi Spinosae Semen), and other medicinal plants. According to the pharmacology of Traditional Chinese Medicine (TCM), Wu Wei Zi and Suan Zao Ren have the ability to relax the mind and promote sleep. When taken together, they may balance the opposing forces of yin and yang. Therefore, ZG may potentially be used as a therapeutic treatment for insomnia. AIM OF THE STUDY This research was specifically developed to establish a strong empirical basis for the subsequent advancement and utilization of ZG in the management of insomnia. This research aimed to gather empirical data to support the effectiveness of ZG, thereby providing useful insights into its potential therapeutic advantages for persons with insomnia. MATERIALS AND METHODS This study utilized Zhumian Granules (ZG), a traditional Chinese herbal decoction, to examine its sedative and hypnotic effects on mice with PCPA-induced insomnia. The effects were assessed using the pentobarbital-induced sleep test (PIST), Morris water maze test (MWM), and autonomic activity test. The levels of neurotransmitters in each group of mice were evaluated using UPLC-QQQ-MS. The impact of ZG on the quantity and structure of hippocampal neurons was seen in brain tissue slices using immunofluorescence labeling. RESULTS ZG was shown to possess active sedative properties, effectively lowering the distance of movement and lengthening the duration of sleep. ZG mitigated the sleeplessness effects of PCPA by elevating the levels of 5-hydroxytryptamine (5-HT), 4-aminobutyric acid (GABA), and 5-hydroxyindoleacetic acid (5-HIAA), while reducing the levels of dopamine (DA) and norepinephrine (NE), as well as decreasing neuronal death. CONCLUSIONS This research confirmed the sedative and hypnotic properties of ZG and elucidated its probable mechanism involving neurotransmitters.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Polygala tenuifolia Willd. has been widely used in the treatment of cancer, forgetfulness, depression and other diseases. AIM OF REVIEW The purpose of this study was to investigate the sleep-enhancing effect and mechanism of P. tenuifolia saponins (PTS). MATERIALS AND METHODS The total saponin (YZ-I) and purified saponin (YZ-II) fractions were extracted and ICR mice model of insomnia was established by p-chlorophenylalanine (PCPA) induction to observe anxiety and depression behaviors. Effects of YZ-I and YZ-II on the levels of neurotransmitters, hormones, and inflammation cytokines were detected by ELISA, RT-qPCR and western blotting. RESULTS The results showed that YZ-I and YZ-II reduced the immobility time of mice and prolonged the sleep time of mice and significantly increased the concentrations of 5-HT, NE, PGD2, IL-1β and TNF-α. YZ-I and YZ-II regulated GABAARα2, GABAARα3, GAD65/67, 5-HT1A and 5-HT2A, while regulated the levels of inflammatory cytokines such as DPR, PGD2, iNOS and TNF-α to exert sedative and hypnotic effects. CONCLUSION PTS are mainly achieved sedative and hypnotic effects by altering serotonergic, GABAergic and immune systems, but the effects and mechanisms of action of YZ-I were different from YZ-II.

Abstract
OBJECTIVE Insomnia is the most common sleep disorder and is often comorbid with mental and physical diseases. The present study was designed to investigate the hypnotic effect of electroacupuncture (EA) of the cymba concha to stimulate the auricular branch of the vagus nerve (ABVN). METHODS Mice were intraperitoneally injected with p-chlorophenylalanine (PCPA, 300 mg/kg·d) for 2 days to induce insomnia and subsequently received EA or manual acupuncture (MA) of the cymba concha for 30 min once daily for 5 consecutive days, or no treatment. The phenobarbital-induced sleep test was used to analyze the hypnotic effects and the open field test was used to analyze the locomotor activities and anxiolytic effects of EA/MA of the cymba concha. In addition, the levels of gamma-aminobutyric acid (GABA) and glutamate (Glu) in the hypothalamus and peripheral blood were determined by enzyme-linked immunosorbent assay (ELISA). RESULTS PCPA injection significantly decreased sleep duration, increased sleep latency and induced anxiety-like behaviors in mice. In PCPA-insulted mice, EA of the cymba concha improved the sleep disturbance by significantly prolonging sleep duration, while no change in sleep latency was observed. Moreover, EA of the cymba concha improved PCPA-induced anxiety-like behaviors without decreasing locomotor activities in the open field test. EA of the cymba concha increased the level of GABA in the hypothalamus and peripheral blood, while Glu concentrations remained unchanged. CONCLUSION These findings indicate that EA of the region innervated by the ABVN upregulates GABA levels in the hypothalamus and ameliorates the symptoms of insomnia and anxiety, suggesting that EA of the cymba concha might have potential value as an intervention for insomnia.

Abstract
BACKGROUND Acanthopanax senticosus (AS) is a medicinal and food plant with many physiological functions, especially nerve protection. Its extract has many functional components, including polysaccharides, flavonoids, saponins, and amino acids. Our previous study indicated that AS extract protected against nerve damage caused by radiation. However, little is known about the gut-brain axis mechanism of AS and its impact on radiation-induced learning and memory impairment. METHOD In 60 Co-γ ray-irradiated mice, we investigated the changes in behavior, neurotransmitters and gut microbiota after different days of administration of AS extract as a dietary supplement. RESULTS The AS extract improved learning and memory ability in mice, and the neurotransmitter levels in the hippocampus and colon started to change from the 7th day, which accompanied changes of the gut microbiota, a decreased abundance of Helicobacter on the 7th day and an increased abundance of Lactobacillus on the 28th day. Among the marker bacteria, Ruminococcus and Clostridiales were associated with 5-HT synthesis, and Streptococcus were associated with 5-HT and ACH synthesis. In addition, the AS extract increased the tight junction protein, inhibited inflammation levels in colon, and even increased the relative protein expression of BDNF and NF-κB and decreased the relative protein expression of IκBα in the hippocampus of irradiated mice. CONCLUSION These results will lay the foundation for further study on the mechanism of the gut-brain axis of AS in preventing radiation-induced learning and memory impairment.

[PMID: 34984694 DOI: 10.1111/jfbc.14075] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2021] [Revised: 12/19/2021] [Accepted: 12/22/2021] [Indexed: 12/18/2022]
Abstract
In China, Armillaria mellea (Vahl) P. Kumm. has been used as a folk medicine to treat insomnia for several hundred years. However, the underlying mechanisms involved are currently unknown. In this study, the anti-insomnia efficacy of A. mellea fermentation liquor (AFL) was evaluated in p-chlorophenylalanine-induced insomnia rats by measuring the serotonergic systems and gut microbiota. Our results demonstrate that all doses of AFL significantly reduced locomotor activity and alleviated decreasing weights in insomnia rats. Further, AFL exhibited better sedative effects by reducing sleep latency and increasing sleep duration in pentobarbital-treated rats. AFL treatment also elevated serum glutathione peroxidase and superoxide dismutase levels, while reducing serum interleukin-6, tumor necrosis factor-α, and interleukin-1β levels. Furthermore, AFL alleviated insomnia by enhancing 5-hydroxytryptamine content and the expression 5-HT1A and 5-HT2A receptor in the hippocampus. Meanwhile, AFL treatment normalized the composition of gut microbiota in insomnia-model rats, while increasing relative abundance of Lachnospiraceae, Ruminococcaceae, and Saccharimonadaceae restores the gut microbial ecosystem altered in insomnia rats. The experiments show that A. mellea alleviated insomnia by modulating serotonergic system and gut microbiota. PRACTICAL APPLICATIONS: Insomnia has become a serious health issue of global concern. As a well-known traditional Chinese medicine, Armillaria mellea has been clinically employed in the treatment of insomnia for centuries in Asia with significant efficacy. In the present study, we firstly reported A. mellea fermentation liquor potentially relieved insomnia rats by alteration of gut microbiota and serotonergic systems and could guide future clinical studies. As a popular edible and medicinal mushroom, A. mellea also can be potentially used in the development and production of novel food products in the future.

Abstract
CONTEXT Lilium davidii var. unicolour Cotton (Lilium genus, Liliaceae) is an edible plant and a herb used in China to alleviate insomnia. OBJECTIVE To investigate the alleviating insomnia mechanism of L. davidii (LD). MATERIALS AND METHODS Wistar rats were intraperitoneally injected with p-chlorophenylalanine (PCPA) to establish an insomnia model. Rats were divided into six groups (n = 8): Control, PCPA, Estazolam (0.5 mg/kg), LD extract in low, medium and high doses (185.22, 370.44, 740.88 mg/kg). Serum hormone levels of the HPA axis, levels of 5-HT, NE and MT, and the expression of GABAA and 5-HT1A receptors in hypothalamus were determined. Moreover, behavioural and pathological changes in the hypothalamus were evaluated. RESULTS After LD administration, body weight and brain coefficient increased by 2.74% and 8.22%, respectively, and the adrenal coefficient decreased by 25%, compared with PCPA group. Elevation of the serum hypothalamic-pituitary-adrenal (HPA) axis hormone CRH (11.24 ± 3.16 ng/mL), ACTH (565.87 ± 103.44 pg/mL) and CORT (44.28 ± 8.73 ng/mL) in the PCPA group was reversed after LD treatment. Furthermore, abnormal excitatory behaviour [5 min movement distance (2096.34 ± 259.51 cm), central exercise time (5.28 ± 1.08 s)] of insomnia rats in the PCPA group was also relieved. LD extract increased 5-HT and MT levels, reduced NE level in the hypothalamus, and upregulated the expression of GABAA R and 5-HT1A. Moreover, LD extract may improve the pathology of neurons in the hypothalamus. CONCLUSIONS LD can be considered to develop health-care food or novel drugs to cope with the increasing number of insomniacs.

Abstract
The current study aimed to establish a rat model of ageing insomnia induced by D-galactose and/or para-chlorophenylalanine. Following establishment of the model, body weights were measured, and Morris water maze and pentobarbital-induced sleep tests were performed. The serum levels of inflammatory mediators and the neural levels of neurotransmitters were detected. The results demonstrated that the body weights of PCPA+D-gal-induced ageing insomnia rats decreased significantly. Ageing insomnia rats exhibited longer latencies to the platform in the Morris water maze tests and fewer target crossings. The sleep latency of the model rats was longer and sleep time was shorter by contrast. The relative expression of hippocampal IL-6, TNF-α, NF-κB and mGluR2 mRNA of the PCPA+D-gal-induced ageing insomnia group was higher, while the relative expression of 5-HT1AR and GABAARa1 mRNA were lower. The serum levels of IL-1β, IL-6, TNF-α and brain level of glutamate increased in the PCPA+D-gal-induced ageing insomnia group, while the levels of 5-HT and GABA decreased. In conclusion, memory function, sleep time, expression of inflammatory factors and neurotransmitters are altered in ageing insomnia rats induced by D-galactose and para-chlorophenylalanine, indicating the successful establishment of a murine model of ageing insomnia.

Abstract
As a Traditional Chinese Medicine (TCM), Shuangxia Decoction (SXD) has been used to treat insomnia in oriental countries for more than thousands of years and it presents remarkable clinical effects. However, its active pharmacological fraction and the mechanism of sedative-hypnotic effects have not been explored. In this paper, we investigated active pharmacological fraction and revealed the detailed mechanisms underlying the sedative-hypnotic effects of SXD. It showed that SXD water extract compared to ethanol extract possessed better sedative effects on locomotion activity in normal mice and increased sleep duration in subhypnotic dose of sodium pentobarbital-treated mice. SXD alleviated p-chlorophenylalanine (PCPA) -induced insomnia by increasing the content of 5-HT in cortex [F (4, 55) = 12.67], decreasing the content of dopamine (DA) and norepinephrine (NE). Furthermore, SXD enhanced the expression of 5-HT1A and 5-HT2A receptors in hypothalamic and reduced serum levels of IL-1,TNF-α [F (5, 36) = 15.58]. In conclusion, these results indicated that SXD produced beneficial sedative and hypnotic bioactivities mediated by regulating the serotonergic and immune system.
